In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p = 10 Pa (= 100 kPa = 1 bar) is recommended by IUPAC, although prior to 1982 the value 1.00 atm (101.325 kPa) was used. There is no standard temperature. Its symbol i… WebAug 20, 2024 · Enthalpy of formation (ΔHf) : The enthalpy change for the formation of 1 mol of a compound from its component elements, such as the formation of carbon dioxide from carbon and oxygen.

WebEnthalpy is a state function, defined by the internal energy (E), the pressure (P) and volume (V) of a system: H = E + PV and ΔH = ΔE + Δ (PV) For enthalpy, there are no method to determine absolute values, only enthalpy changes (ΔH values) can be measured.
